This failure to provide a readable vocabulary is not a trivial defect of modernist styles: it is the reason why modernist buildings fail to harmonize with their neighbors. In architecture, as in music, harmony is a relation among independently meaningful parts, an achievement of order from elements that create and respond to valency. There are no chords in modernist architecture, only lines—lines that may come to an end but that achieve no closure.
